On the Design of a 2D Array HF Skywave Radar

open access: yes, 2008
New generation of HF skywave radars moves toward 2D array solution to get high signal to noise ratio (SNR), low probability of intercept (LPI), precise electronic scanning, faster scanning time. Critical elements for the design of such a system are radar
